3.0 INSTALLATION

3.1 General Installation Notes

• Read through the entire installation section ﬁrst

before beginning installation.

• Do not install in locations where water can enter

the controller.

• Loose power connections and/or corroded wires

may result in resistive connections that melt wire

insulation, burn surrounding materials, or even

cause ﬁre. Ensure tight connections.

• F

or good service life, extreme temperatures and

marine environments should be avoided.

WARNING: Solar and battery fuses or DC

breakers are required in the system. These

protection devices are external to the EcoPulse

controller, and must be a maximum of 15

Amps for the EcoPulse-10/M, 30 Amps for

the EcoPulse-20/M, and 40 Amps for the

EcoPulse-30/M.

WARNING: All breakers must be properly rated

for wire ampacity, which may require less than

the maximum breaker sizes referenced above.

WARNING: Minimum over-current protection

device interrupt ratings must be 2000A

for 12V systems, and 4000A for 24V systems.

NOTE: Carefully observe the LEDs after

each connection. The LEDs will indcate

proper polarity, and a secure co nnection.

3.2 Conﬁguration

The DIP switch block shown below is used to set the

operating parameters for the EcoPulse.

Switch 1: Lighting Control

With DIP 1 ON, a light connected to the load

terminals will be ON from dusk-dawn.

Switch 7: Battery Equalization

Mode Switch 7

Manual Equalization OFF

Auto Equalization ON

NOTE: Regardless of DIP 7 setting, manual EQ can be initiated using

the on-board meter command, "Start Equalize". For non-meter

versions, DIP 7 only enables or disables auto equalization - manual EQ

is not available.

Switch 8: Current Switching

Mode Switch 8

PWM switching OFF

Slow switching ON

The default (PWM) switching setting (OFF / down) operates

at 300Hz. If load or system noise is an issue, DIP 8 can be set

(ON-up) for slow switching at 1Hz. Standard PWM switching is

recommended when system noise is not a problem.

3.3 Mounting

Inspect the controller for shipping damage. Mount the

EcoPulse to a vertical surface (4-#8 zinc-plated self-

tapping screws are included). Tighten the mounting

screws using care not to crack the plastic case. Do not

install directly over an easily combustible surface since

the heat sink may get hot under certain operating

conditions.

NOTE: The heat sink must be in a vertical

position (ﬁns up and down).

Table 3.1. Battery charging settings for each selectable battery type

If the system voltage DIP Settings Switches are set

to Auto-detect, battery voltage over 15.5V will be

detected as a 24V nominal battery, and the unit will

charge accordingly.

The 12/24V auto selection is done only at start-up,

and the detected system voltage will never change

during operation. It is recommended to set DIPs 2

and 3 to the correct system voltage setting. Only use

the default auto-detect setting if the nominal system

voltage is not known.

Switches 4, 5, 6: Battery Type Selection

Preset EcoPulse battery charging options are shown

in table 3-1 below. All voltage settings listed are

for nominal 12 Volt batteries. Multiply the voltage

settings by two (2) for 24 Volt systems.

NOTE: These settings are general guidelines for use

at the operator’s discretion. Consult the battery

manufacturer for optimal battery charge settings.

STEP 1: Check Controller Limitations

Verify that the highest temperature compensated solar

array open-circuit voltage (Voc), and load current do

not exceed the ratings of the EcoPulse version being

installed.

STEP 2: Remote Temperature Sensor

WARNING: Risk of Fire.

If no Remote Temperature Sensor (RTS)

is connected, use the EcoPulse within 3m

(10ft) of the batteries. Internal Temperature

Compensation will be used if the RTS is

not connected. Use of the RTS is strongly

recommended.

Connect the RTS to the 2-position terminal located

(see ﬁgure). There is no polarity, so the (+) or (-) can

be connected to either screw terminal.

WARNING: Equipment Damage.

Never place the temperature sensor inside

abattery cell. Both the RTS and the battery

will be damaged.

CAUTION: The EcoPulse will use the local

temperature sensor for compensation if the RTS

is not used.

STEP 3:

Grounding

NOTE: Depending on the country of

installation, conductors identiﬁed by the

color green, or a combination of green /

yellow, shall only be used for earthing

conductors.

For safety, and effective lightning protection, it is

recommended, and may be locally required, that

the negative conductor of the charging system be

properly grounded. Use only one system earth

ground. For conductor sizing requirements, refer to

the U.S. National Electrical Code, or applicable local

regulations or code.

4.1 Battery Charging Information

4-Stage Charging

The EcoPulse has a 4-stage battery charging algorithm

for rapid, efﬁcient, and safe battery charging. Figure

4-1 below, shows the sequence of stages.

Figure 4.1. EcoPulse Charging Algorithm

Bulk Charge Stage

During Bulk charging, the battery is not at 100% state

of charge and battery voltage has not yet charged to

the Absorption voltage set-point. The controller will

deliver 100% of available solar power to recharge the

battery.

VOLTAGE

TIME

Absorption Stage

When the battery has recharged to the Absorption

voltage set-point, constant voltage regulation is

used to maintain battery voltage at the Absorption

set-point.

Float Stage

After the battery is fully charged in the Absorption

stage, the EcoPulse reduces the battery voltage to

the Float voltage set-point. The purpose of ﬂoat is to

protect the battery from long-term overcharge.

Equalization Stage

WARNING: Risk of Explosion.

Equalizing vented batteries produces

explosive gases. The battery bank must be

properly ventilated.

CAUTION: Equipment Damage.

Equalization increases the battery voltage

to levels that may damage sensitive DC

loads. Verify all system loads are rated for

the temperature compensated Equalize

voltage before beginning an Equalization

charge.

CAUTION: Equipment Damage.

Excessive over-charging and gasing too

vigorously can damage the battery plates

and cause shedding of active material from

the plates. An equalization that is

too high, or too long, can be damaging.

Review the requirements for the particular

battery being used in your system.

Equalization (EQ) charging raises the battery voltage

above the standard absorption voltage so that the
